DNSSEC Adoption Part 1: A Status Report

Where is the domain industry with the adoption of DNSSEC? After a burst of well publicized activity from 2009-2011 -- .org, .com, .net, and .gov adopting DNSSEC, roots signed, other Top-Level Domains (TLDs) signed -- the pace of adoption appears to have slowed in recent years. As many CircleID readers know, DNSSEC requires multiple steps in the chain of trust to be in place to improve online security. more

Paul Vixie on How the Openness of the Internet Is Poisoning Us

In a video interview conducted during the NSCS ONE conference, Paul Vixie CEO of Farsight Security further discusses the topic of his presentation titled: "Defective by Design -- How the Internet's Openness is Slowly Poisoning Us". more

The Challenge of DNS Security

When the domain name system (DNS) was first designed, security was an afterthought. Threats simply weren't a consideration at a time when merely carrying out a function - routing Internet users to websites - was the core objective. As the weaknesses of the protocol became evident, engineers began to apply a patchwork of fixes. After several decades, it is now apparent that this reactive approach to DNS security has caused some unintended consequences and challenges. more

If You Build It, They Will Come.

Only two years after signing the DNS root zone, the powerful lure of a secure global infrastructure for data distribution is starting to reveal itself. It is illustrated clearly by two proposed technical standardizations that seek to leverage secure DNS. To some degree these developments highlight the strength of DNS institutions and how they might fill gaps elsewhere in the Internet's governance. But an increasing reliance upon and concentration of power in the DNS also makes getting its global governance correct even more important. more

Driving DNSSEC: The Need for Integration of All the Functions Needed

DNSSEC continues to gain momentum as network operators and domain owners watch and learn from early adopters. The learning process is made easier by efforts such as the ongoing work conducted by researchers at Sandia labs to methodically identify and categorize the kinds of problems that are occurring. more

The Christmas Goat and IPv6 (Year 2)

Last year the municipality of Gavle asked my company if we could help them load share the streaming pictures of the famous Christmas goat in Gävle. I accepted the invitation and set up a separate domain. My own interest in this was of course to track the usage of IPv6 and validation of DNSSEC from the visitors of the site. more

The Real Deployment Issue

When I see glib talk about the inevitable transition to IPv6 or DNSSEC, I have to wonder what industry people think they are working in. Let me give an example that has nothing to do with networking: storage capacity. Now if there is one constant that everyone in the computing industry can agree on it is that they expect storage media capacity to increase. more

The Dark Internet

I consult on communication issues for Neustar, an Internet infrastructure company. As most CircleIDers know, Neustar works behind the scenes to ensure the smooth operation of many critical systems like DNS, .us and .biz, local number portability and digital rights management. One of the cool things about working for them is the chance to attend the events they sponsor. Last week Neustar held a security briefing for senior federal IT personnel focused on Cybersecurity and Domain Name System Security Extensions (DNSSEC)... more

DNSSEC vs DDoS Protection: Is It Really a Choice?

Within the last year or two, I've heard people express an opinion to the effect that if the domain name industry put as much focus on preventing distributed denial of service attacks as we have on implementing DNSSEC, the Internet would be a safer place. While there may be a grain of truth there, I suggest that this kind of thinking presents us with something of a false dichotomy. more

DNS Platforms: A Study in Capacity and Scalability

Capacity and scalability are necessary in managing DNSSEC and D/DoS. Capacity, necessary for maintaining operations during D/DoS attacks, is also necessary for increased traffic due to DNSSEC deployment. Scalability is highly important, as DNSSEC is deployed not only will greater traffic levels will be encountered, greater demand will be placed on the DNS platform. In the interest of understanding both capacity and scalability CommunityDNS conducted tests to assess the readiness of the two main DNS server platforms, BIND and NSD... more

What is ‘On-Tap’ at ICANN 38 - Brussels (There’s More to Belgium than Beer!)

As the shorter of the ICANN interregnums comes to a close and the ICANN faithful finalize their dinner reservation agendas for Brussels, it is time again for a preview of what will be 'on-tap' at next week's ICANN meeting. While, as always, there is a lot going on in ICANN Land, a scan of the blogosphere and ICANN list serves suggests that the four most discussed topics will be... more

Deploying DNSSEC: Lessons from Domain Registrar Implementation

As a registrar at the front end of the DNSSEC deployment effort, our technical team has made a sustained investment in DNSSEC deployment so that our customers don't get overwhelmed by this wave of changes to the core infrastructure of the Domain Name System. Along the way, we've learnt a lot about how to implement DNSSEC which might hold useful lessons for other organizations that plan to deploy DNSSEC in their networks. more

Operational Challenges When Implementing DNSSEC

As a reader of this article, you are probably familiar with the DNS cache poisoning techniques discovered a few years ago. And you have most likely heard that DNSSEC is the long term cure. But you might not know exactly what challenges are involved with DNSSEC and what experience the early adopters have gathered and documented. Perhaps you waited with our own rollout until you could gather more documentation over the operational experience when rolling out DNSSEC. This article summarizes authors' experiences and learnings from implementing the technology in production environments as well as discusses associated operational issues. more

Swiss Among World Leaders in Enabling DNSSEC

SWITCH, the registry for .CH and .LI domain names, enabled DNSSEC on day two of the annual Domain Pulse conference in Luzern yesterday. SWITCH became the third ccTLD registry to enable DNSSEC giving registrants of .CH domain names added security following .SE (Sweden) and .CZ (Czech Republic). more

Why DNS Is Broken, Part 2: DoS Target

Before we get into what DNSSEC is and the benefits of it, let's talk about some of the other potential pitfalls of DNS. One of the most significant issues we have to deal with are denial-of-service (DoS) attacks. While DoS attacks are not specific to DNS we have seen DNS be a frequent target of these attacks. more
